> It's not an apt descriptor at all because there's no test for a normal range of a chemical that depressed people are outside of.
As disconcerting as it may be, subjective feeling is a range (google "pain indicator charts") as well as professional (for some value of that) psychological analysis.
It may be a minority view but only because of people's blind faith in a medical authority's ability to distinguish a patient's mind as 'abnormal'. What Barrin92 said is logically sound, an empirical diagnosis of the behavior coming from an individual is not a very precise measure of any type of chemical imbalance. That's not to say individuals suspected to have of mental illness shouldn't get treated, but that medical professionals shouldn't jump to medications as a primary end-all treatment (which is what I believe is what the linked article was trying to say).

I think your view is minority view.
